1969 426 Hemi that was recently rebuilt.

With 10W-40 oil and a mechanical pressure gauge, at 180 temp I am seeing around 15-17lbs of oil pressure at idle at approx 800 rpm, rev the motor up to 2000rpm and the pressure quickly rises with the RPM to 55 to 60lbs.
Wondering if that 15lbs at idle is going to be a problem?
Thanks,
Wolf
